VAH 2020- wait times?

Thinking about going to Villains after hours on February 21st. Only park visit on a quick trip. Main reason would be so my son who loves Snow White right now could ride 7DMT train several times, will the wait times for 7DMT be short and make the trip worth it?

We went to VDAH two days ago. Waited until 10:45 or so to ride 7D and waited about 15 minutes. I would imagine if we had continued to ride during the 11-12 hour (the last hour of the event) wait times would’ve gotten shorter.
